.TH NEWROLE "1" "October 2000" "Security Enhanced Linux" NSA
.SH NAME
newrole \- run a shell with a new SELinux role
.SH SYNOPSIS
.B newrole
[\fB-r\fR|\fB--role\fR]
\fIROLE\fR
[\fB-t\fR|\fB--type\fR]
\fITYPE\fR
[\fB-l\fR|\fB--level\fR]
[\fB-p\fR|\fB--preserve-environment\fR]
\fILEVEL\fR [-- [\fIARGS\fR]...]
.SH DESCRIPTION
.PP
Run a new shell in a new context.  The new context is derived from the 
old context in which
.B newrole
is originally executed.  If the
.B -r
or
.B --role
option is specified, then the new context will have the role specified by
\fIROLE\fR.
If the 
.B -t
or
.B --type
option is specified, then the new context will have the type (domain)
specified by
\fITYPE\fR.
If a role is specified, but no type is specified, the default type is derived
from the specified role.  If the
.B -l
or
.B --level
option is specified, then the new context will have the sensitivity level
specified by
\fILEVEL\fR.
If
\fILEVEL\fR
is a range, the new context will have the sensitivity level and clearance
specified by that range.  If the
.B -p
or
.B --preserve-environment
option is specified, the shell with the new SELinux context will preserve environment variables,
otherwise a new minimal environment is created.
.PP
Additional arguments
.I ARGS
may be provided after a -- option,
in which case they are supplied to the new shell.
In particular, an argument of \-\- \-c will cause the next argument to be
treated as a command by most command interpreters.
.PP
If a command argument is specified to newrole and the command name is found
in /etc/selinux/newrole_pam.conf, then the pam service name listed in that
file for the command will be used rather than the normal newrole pam
configuration.  This allows for per-command pam configuration when
invoked via newrole, e.g. to skip the interactive re-authentication phase.
.PP
The new shell will be the shell specified in the user's entry in the 
.I /etc/passwd
file.
.PP
The
.B -V
or 
.B --version
shows the current version of newrole
.PP
.SH EXAMPLE
.br
Changing role:
   # id \-Z
   staff_u:staff_r:staff_t:SystemLow-SystemHigh
   # newrole \-r sysadm_r
   # id \-Z
   staff_u:sysadm_r:sysadm_t:SystemLow-SystemHigh

Changing sensitivity only:
   # id \-Z
   staff_u:sysadm_r:sysadm_t:Unclassified-SystemHigh
   # newrole \-l Secret
   # id \-Z
   staff_u:sysadm_r:sysadm_t:Secret-SystemHigh

.PP
Changing sensitivity and clearance:
   # id \-Z
   staff_u:sysadm_r:sysadm_t:Unclassified-SystemHigh
   # newrole \-l Secret-Secret
   # id \-Z
   staff_u:sysadm_r:sysadm_t:Secret

.PP
Running a program in a given role or level:
   # newrole \-r sysadm_r \-\- \-c "/path/to/app arg1 arg2..."
   # newrole \-l Secret \-\- \-c "/path/to/app arg1 arg2..."
